The following scenario has me confused. In my main program I have:-
<?php
$link = '';
.....snip......
?>
in an included function I have
<?php
function PMConnect() {
global $dbservertype, $servername, $dbusername, $dbpassword, $dbname, $link;
$link = mssql_connect("$servername", "$dbusername", "$dbpassword");
if (!$link) {
sprintf($Message, "At %d in %s Could not connect to %s at %s as %s",__LINE__, __FILE__, $dbname, $servername, $dbusername);
trigger_error(E_USER_ERROR, $Message);
}
if (!(mssql_select_db("$dbname", $link))) {
sprintf($Message, "At %d in %s Could not select %s at %s as %s",__LINE__, __FILE__, $dbname, $servername, $dbusername);
trigger_error(E_USER_ERROR, $Message);
}
echo "In PMConnect() link = $link<br>";
}
?>
and here the echo shows that $link contains data but now in another included function I have
<?php
function GetActive($Datum) {
global $link;
echo "In GetActive() link = $link<br>";
.....snip......
this echo shows that $link is empty.
NB. All my functions are contained within .inc files that are incorporated via something similar to include('includes/PMConnect.inc');
What am I misunderstanding ?
